Donald J. and Melania Trump are accustomed, I presume, to some pretty sumptuous living quarters. They’re accustomed to glitz and glam, of which they have plenty at their various homes in New York, south Florida and New Jersey.

They have taken up part-time residence in an old house at 1600 Pennsylvania Ave. Trouble is, though, the president thinks it’s a “real dump.” He made the remark to golf pals; Trump, as is customary, denies saying it.

Hey, not to worry. The first couple and their young son are now spending the next 15 or so days at their golf club in New Jersey. The “dump” in D.C. is getting a little fixup while they are away: a new heating and air conditioning system and some nips and tucks here and there throughout the residence.

Still, for millions of Americans who’ve seen the White House up close — as my wife, sons and I have been honored to do — the “real dump” comment is offensive to the core.

It’s been the home for presidents since John Adams. Yes, it got burned during the War of 1812. Presidents since that time have been forced to fix things up at the place. President Truman moved into the Blair House with his wife and daughter while crews repaired some flooring. President Clinton had some asbestos issues. The White House has been plagued by flies on occasion, too.

It’s not a “dump,” let alone a “real dump,” as Trump has called it.

Sure, the place is old. It needs repair on occasion. A “dump”? Hardly. It’s filled with history and its walls contain portraits of all the men and women who have called it home.

If only the current president could appreciate it. Maybe he will if the heating and AC are in proper working order when he returns from his vacation.
